Answer:
Explanation:
Let lift force F be created by propellers at angle of Ф with the horizontal .
The vertical component of this force will balance the weight of helicopter and horizontal component will balance the air resistance .
F sinФ = mg = 2750 x 9.8 = 26950 N
F cosФ = 7510 N
Squaring and adding ,
F² = 26950² + 7510²
= 726302500 + 56400100
= 782702600
F = 27976.82 N .
Answer:
No, not at all. This kinetic energy of car is converted/lost in the form of sound and heat under the tyre when driver apply brakes.
Explanation:
This law states that energy can neither be created nor destroyed but it changes from one form to the other.
In this case reduction of kinetic energy of car does not contradict the law but it changes into heat and sound energy. When driver apply brakes we hear the sound of Tyre due to friction with the road. The tyre become hot too.
So it is not in contradiction to the law of conservation of energy (First Law of Thermodynamics).
